Those humans who use and study the English Language have supplied the general public with Webster's Dictionaries.
And the reason they're always updating dictionaries is because words change. The reason they change? The people speaking them use them differently. A hundred years ago 'nigger' was just an everyday word for a black person. Now it's extremely offensive, and not just to black people. It's offensive because the majority of people speaking English believe it to be so; they assign it its meaning.
And it goes the other way, too.
The Catcher in the Rye was banned by many schools because of its use of the word 'fuck', which in the fifties was highly inappropriate. Nowadays, it ain't so bad. It's all over books and movies. You even hear it on TV from time to time, unbleeped.
It's not old, rich, highbrow "scholars" who control a language. It's everyday people. The "scholars" merely record it.
